How do I achieve turn by turn navigation on AI2?

Ok nice to know. Not obviously mentioned in documentation (

ResponseContent The raw response from the server. This can be used to access more details beyond what the GotDirections event provides.) and not terribly useful because the ORS directions themselves are insufficient and unreliable in my experience. The process to extract individual coordinates is convoluted and awkward. You may want to include your more detailed explanation in the documentation.

The difference between the Google api and ORS is the difference between a Cadillac and a bicycle.
